In this paper we outline a post-processing system for compressed video sources, aimed at reducing the visibility of coding artifacts. To achieve optimal video quality for compressed sources, it addresses artifact reduction and video enhancement functions as well as their interdependency. The system is based on the Unified Metric for Digital Video Processing (UMDVP), a quality metric that estimates the level of coding artifacts on a per-pixel basis. Experiments on MPEG-2 encoded video sequences showed significant improvement in picture quality compared to systems that do not have UMDVP control or that do not consider the interdependency between artifact reduction and video enhancement.
